bined Lubricator and Throttle -Valve, of

1 which the following is a specification.

chine, the lubricant being fed into the latter through the medium of the fluid passing through the valve.

To these ends the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a section through the valve embodying my invention, taken on the line 1. 1. of Fig. 2. Fig. 2 is a section through the valve on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1 with the valve removed.

Referring to the drawings, 1 designates a valve-casing having a steam passage or duct 2 therethrough and coupled or connected at one end by a pipe 3 with the cylinder 4 of a drilling-machine and at the other end, by means of a hose 5 or the like, with an engineboiler. (Not shown.) These parts, except as hereinafter explained, may be oi the usual or any appropriate construction and material, inasmuch as they constitute no part ol" my invention.

Provided within the casing 1 and trans versely of the duct 2, about midway between. the end of the latter, is avalve opening or seat 6,having mounted for rotation therein. a plug or throttle valve 7, provided at its outer end with an operating-handle 8 and between its ends with an opening or passage 9, adapted upon rotation of the valve to be moved into and out of register with the duct 2 for open ing or closing the latter. The casing l has also formed therein an enlarged chamber or reservoir 10, designed in practice to receive a supply of lubricant, which may be introduced. thereto through openings 11, normally closed by screw-plugs or other suitable closures 12, there being provided through the division-wall or partition 13 between the reservoir and duct 2 feed openings or passages 14, normally closed by the valve 7 and through which the oil may, when the valve is properly adjusted, escape from the reservoir into the d not 2.

in practice, su 'iposing the valve to be adjusted to the position shown in Fig. l, the steam or other [luid under pressure may pass from the source of supply through the duct 2 to the drillinganachine, attention being directed to the fact that under these conditions the valve 7 will serve to just close the passages 14 for cutting oil supply of lubricant from the reservoir 10. hen, however, it is necessary or desirable to iced lubricant to the cylinder of the drilling-machine, the valve may be slightly turned to permit the lubricant to escape from the reservoir through the passages 14 and into the duct 2, where it will be taken up and carried by the motive fluid into the cylinder 4-, it being apparent that the valve may be moved suiii ciently to open the passages 141; without atiecting the passage 01 the :[iuid through the duct. l/Vhen it is desired to cut oil the supply of steam or fluid to the cylinder 4- iior stopping the drill, the valve may, without opening the passages H, be turnedv to the position indicater'l by dottml lines in Fig. 1 for closing the duct 2.

In order that the operator may readily determine the necessary movement oi the valve for opening the passages 1 -11, provide a pair of pointers or indicators 15 16, preferably in the form oi projections, as shown, lormed, respectively, upon the valve and. its easing. These projections are of a width equaling the amount oil. movement necessary for opening the passages and normally stand in alinement, it being obvious that when the valve is rotated in the proper direction until the pointers move out of alinement the passages will be opened.

casing which constitutes the oil-chamber; said valve being operable at will for opening 15 the oil-passage without closing the fluid-duct, for opening the passage and closing the duct, or for closing both the passage and the duct. In'testimony that I claim the foregoing as my own I have hereto aflixed my signature 20 in the presence of two witnesses.
